Heatwave danger for seniors: sudden temperature changes are just as dangerous as the heat itself

Heatwaves and the hidden risks for elderly people

Heatwave periods pose a genuine threat to the health of older adults; however, doctors warn that high temperatures are not the only concern. Sudden transitions from outdoor heat to air-conditioned homes, shops, or vehicles can be equally harmful to the body, particularly in the case of elderly people.

The warning from cardiology specialists

Cardiology specialists emphasise that rapid temperature changes place the heart and cardiovascular system under significant stress. For older adults, whose adaptive mechanisms are already weakened by age or chronic conditions, this stress can trigger serious episodes, including heart attacks or strokes.

Common mistakes made by seniors during summer

• Entering a heavily cooled room abruptly after prolonged exposure to the sun
• Setting the air conditioning to very low temperatures, with differences of more than 8–10 degrees compared to outside
• Sitting in front of a fan or air conditioning unit whilst wearing sweat-dampened clothing
• Stepping suddenly into outdoor heat after spending hours in cool spaces

Recommendations for protecting your health during heatwaves

Doctors recommend that the temperature difference between indoors and outdoors should not exceed 7–8 degrees Celsius. Additionally, older adults should avoid going outside between 11:00 and 17:00, stay properly hydrated, and wear light clothing made from natural fabrics. Before entering a cool space, a brief period of acclimatisation is advisable.

Family members and carers of elderly people must remain alert to signs of dehydration or heat stroke, such as dizziness, nausea, pallor, or loss of consciousness, and should seek emergency medical assistance at the very first warning sign.
